Definitions
- the invention relates to an apparatus for dampening of acoustic noise generated by air-cooling of at least one wind turbine component provided with the nacelle of a wind turbine.
- Air-cooling of wind turbine components provided with the nacelle, e.g. electric generators, of wind turbines is a common approach for cooling respective wind turbine components.
- a device for air-cooling creates a concerted flow of a cooling gas, e.g. air, through respective cooling channels provided with the wind turbine component.
- the cooling gas typically is blown or sucked out of the nacelle of the wind turbine, i.e. the cooling gas is blown or sucked through an opening provided with the nacelle of the wind turbine.
- the object is achieved by an apparatus for dampening of acoustic noise generated by air-cooling of at least one wind turbine component provided with the nacelle of a wind turbine, with the apparatus comprising at least one acoustic dampening means, with the acoustic dampening means comprising at least one acoustic dampening channel structure having at least one acoustic dampening channel connected with at least one inlet opening of the acoustic dampening channel structure and at least one outlet opening of the acoustic dampening channel structure.
- the present invention suggests an apparatus allowing for an effective and reliable dampening of acoustic noise generated by air-cooling of wind turbine components provided with the nacelle of a wind turbine.
- Such wind turbine components are an electric generator, a, particularly mechanical or hydraulic, transmission means disposed between the or an electric generator and a rotor hub, a, particularly mechanical or hydraulic, rotor blade pitching means for pitching rotor blades, a braking means for braking rotation of the or a rotor hub, or a control unit, for instance.
- a respective electric generator may be a direct driven generator which may be attached to an end part, flange, main shaft and/or bearing of the nacelle.
- Wind turbine component provided with the nacelle of a wind turbine.
- the apparatus comprises at least one acoustic dampening means which allows for dampening of acoustic noise or acoustic emissions generated by air-cooling of a respective wind turbine component or directly or indirectly related to air-cooling of a respective wind turbine component.
- the at least one acoustic dampening means is adapted to realise an acoustic dampening effect, i.e. a reduction of acoustic noise directly or indirectly originating from air-cooling of a respective wind turbine component.
- the acoustic dampening means comprises at least one acoustic dampening channel structure having at least one acoustic dampening channel connected with or communicating with at least one inlet opening of the acoustic dampening channel structure and at least one outlet opening of the acoustic dampening channel structure.
- the acoustic dampening channel structure comprises respective, particularly tube-like, wall elements defining at least one, typically longitudinal, acoustic dampening channel through which a cooling gas may flow. Therefore, a respective acoustic dampening channel may be perceived as a flow channel.
- the cross-sectional shape of a respective acoustic dampening channel may be rectangular. However, other cross-sectional shapes, e.g. circular, elliptic, or oval shapes, are also feasible.
- the cross-section of a respective acoustic dampening channel may vary along the length of its course, i.e. between a respective inlet opening and a respective outlet opening. If the acoustic dampening channel structure comprises a plurality of acoustic dampening channels, the acoustic dampening channels may be at least partially provided with the same or different cross-sections.
- the flow of a respective cooling gas has to be directed in such a manner so as to enter the acoustic dampening channel structure at respective inlet openings, flow through at least one acoustic dampening channel of the acoustic dampening channel structure, whereby a reduction of acoustic noise is realised, and exit the acoustic dampening channel structure at respective outlet openings.
- acoustic dampening channels e.g. fans, ventilators, etc., may be provided which allow for blowing and/or sucking the cooling gas through the acoustic dampening channel structure.
- the acoustic dampening channel structure comprises a plurality of, i.e. at least two, separate acoustic dampening channels.
- different configurations of respective inlet openings, outlet openings, and acoustic dampening channels extending between respective inlet openings and outlet openings are possible.
- the acoustic dampening channels may be connected with a common inlet opening and with a common outlet opening.

- each acoustic dampening channel is connected with a separate inlet opening and with a separate outlet opening.
- each acoustic dampening channel may have its own inlet opening and its own outlet opening, i.e. each acoustic dampening channel may communicate with its own inlet opening and with its own outlet opening.
- the acoustic dampening channels or a group of at least two acoustic dampening channels are connected with a common outlet opening and with separate inlet openings.
- the acoustic dampening channels may have the same outlet opening and different inlet openings, i.e. the acoustic dampening channels may communicate with a common outlet opening, whereas they may communicate with different inlet openings.
- the acoustic dampening channels or a group of at least two acoustic dampening channels are connected with a common inlet opening and with separate outlet openings.
- the acoustic dampening channels may have the same inlet opening and different outlet openings, i.e. the acoustic dampening channels may communicate with a common inlet opening, whereas they may communicate with different outlet openings.
- This embodiment is of particular interest since it has been observed that splitting the acoustic dampening channel structure in respective separate acoustic dampening channels after a single inlet opening, may result in a significant reduction of acoustic noise.
- an acoustic dampening channel structure comprising a plurality of acoustic dampening channels
- at least two acoustic dampening channels have the same or differently orientated courses.

- the orientation of the courses of respective acoustic dampening channels may differ, i.e. at least two acoustic dampening channels may have different courses. This may be realised by a non-parallel arrangement of respective acoustic dampening channels of the same shape or by an arrangement of acoustic dampening channels having different shapes, for instance.
- the course of a respective acoustic dampening channel is mainly defined by its longitudinal extension between a respective inlet opening and a respective outlet opening and/or spatial modifications of its longitudinal extension relative to a straight reference axis.

- the two acoustic dampening channels have oppositely curved courses relative to each other.
